Sayang, I'm so sorry you're going through this, it's scary, especially with first baby. Tapi please jangan stress lagi, kena jumpa doctor atau go to the hospital scanning department today if possible. Heartbeat visibility at 11 weeks should be clear, so you really need proper medical assessment, bukan online advice boleh sort this out. A few of my mum friends went through uncertain scans too, and the doctor did follow-up ultrasounds or blood tests to confirm what's happening. You're not alone in this, but you need professional care now, okay? Sending you strength
